If the components were all individually grounded, this could lead to voltage potential differences. The AC output terminals of the inverter supply the Neutral to Ground connection, and no secondary grounding connections are permitted. See also: Connect A Solar Panel To An Inverter (Here’s How)
The inverter AC output terminals supply the Neutral to Ground connection and no other such connections are permitted. All Ground Fault detectors do not need a ground wire connection as they sense differential current between Hot and Neutral. Ground wires are there to prevent equipment enclosures, aka “housings”, from becoming energized.
Inverters are enclosed with an Aluminum heatsink to dissipate heat and are also fitted with a grounding terminal to the enclosure. A grounding wire of 6 AWG must be connected to the grounding terminal on the inverter and connected to a single-point grounding connection wire.
Some modern inverters are fitted with a grounding point connection in the inverter circuitry. Still, this grounding point must be disconnected when the inverter is connected to a power distribution panel with its grounding. The inverter must not be double grounded as this may cause a problem.
